What really was that thing at the center of the galaxy, and was the Great Barrier a natural phenomenon or something constructed to contain it? The creature says it has been “imprisoned…” Is that literal, or has it just been trapped there? How did it influence Sybok?
It must have had an amazing range if it could influence him back on Nimus III but I wonder if it had reached out to him back on Vulcan. Yeah but the how and the why would make for an interesting story or two.
